  • Circuit for driving a solenoid
    Patent number: 6657845
    Abstract: A series circuit including a diode for refluxing and a capacitor is connected in parallel to a solenoid coil, and a light-emitting diode is connected in parallel to the capacitor. A negative voltage appearing across the solenoid coil because of an induced electromotive force generated in the solenoid coil can be attenuated and a fall time of current flowing into the solenoid coil can be shortened.
    Type: Grant
    Filed: March 26, 2001
    Date of Patent: December 2, 2003
    Assignee: Nippon Control Industrial Co., Ltd.
    Inventors: Kazuo Kanomata, Teruya Sawada, Takashi Nakamura
